What is the composition of CNC machining center? CNC machining center, with high precision and high machining efficiency, can complete multiple processes. CNC machining center has the functions of engraving, milling, engraving, drilling and tapping. It has complete functions and a wide range of applications. It is suitable for Jingmi processing of various parts and components, and is widely used in a wide range of industries. What are the basic components of CNC machining center? So today, let’s talk about the content of “what is the composition of CNC machining center”, hoping to help you.

What is the composition of CNC machining center?
1. Foundation components: it is composed of bed, column, workbench and other components.
2. Spindle components: it is composed of spindle box, spindle motor, spindle and spindle bearing.
3. Feed mechanism: it is composed of feed servo motor, mechanical transmission device and displacement measuring element.
4. Numerical control system: the numerical control part of the machining center is composed of numerical control device, PLC, servo control device and operation panel.
5. Automatic tool changer system: automatic tool changer (ATC) is composed of tool magazine, manipulator and other components.
6. Auxiliary devices: auxiliary devices include lubrication, cooling, chip removal, protection, hydraulic, pneumatic and detection systems.

What are the components and functions of CNC machining center?
1. Function of basic components: it mainly bears the static load of the machining center and the cutting load generated during machining. Therefore, it must have sufficient strength These large pieces are usually cast iron or welded pot structural parts It is the basic component of volume and mass Zui in machining center.
2. Function of spindle components: the start, stop, speed change and other actions of the spindle are controlled by the numerical control system, and participate in the cutting movement through the daoju installed on the spindle. It is the power output part of cutting processing.
3. Function of feed mechanism: drive the moving parts such as worktable to form feed motion.
4. The function of CNC system: the control center to complete the machining process.
5. Function of automatic tool change system: automatic tool change. When the tool needs to be changed, the CNC system sends a command, and the manipulator (or through other means) takes daoju out of the tool magazine and loads it into the spindle hole.
6. Function of auxiliary devices: Although these devices do not directly participate in the cutting movement, they play a role in maintaining and reducing the machining efficiency, machining accuracy and reliability of the machining center Therefore, it is also an indispensable part of the machining center.

How to maintain the basic components of CNC machining center?
1. Strictly formulate and implement the management system of daily maintenance of CNC system software of machining center: strictly formulate the management system of daily maintenance of CNC system software according to the characteristics of different machining centers, and strictly abide by it in application and actual operation.
2. Try to avoid opening the cabinet door of CNC machine tool and the door of strong current cabinet: as the gas in the machining and manufacturing workshop usually contains welding smoke and floating dust, once they fall into the printed circuit board or electrical components of CNC machine tool, it is easy to reduce the grounding resistance of electronic components and even cause the destruction of PCB circuit board or electrical components. Therefore, try to avoid opening the cabinet door of CNC machine tool and the door of strong current cabinet.
3. Regularly clear the heat pipe heat dissipation and exhaust system of CNC machine tool equipment in the machining center to avoid overheating of CNC machine tool equipment: the heat pipe heat dissipation and exhaust system is the key equipment to avoid overheating of CNC machine tool equipment. Therefore, check whether each radiator fan in the CNC machine tool cabinet operates normally every day, check whether the primary air duct filter device is blocked in half a year or a quarter, and if so, remove it immediately.
4. Pay attention to the maintenance of the input / output equipment of the CNC system software of the machining center: for example, the cleaning of the tape drive in the input equipment of the CNC system software.
5. Regular maintenance and replacement of DC motor brushes: most of the processing centers manufactured in the initial stage use DC servo motors, which has the problem of damage to carbon brushes. Therefore, for DC servo motors, DC motor brushes must be maintained and replaced regularly.
6. Often monitor the working voltage of the power grid used by CNC equipment: the CNC of the machining center has strict regulations on the working voltage of the power grid in the system work. For example, some CNC system software allows the working voltage of the power network to fluctuate within the range of 85% ~ 110% of the rated current, otherwise the CNC system software will not work normally, and even the electronic components inside the CNC system software will be damaged. Therefore, the working voltage of the power network should be often checked and controlled within – 15% ~ 10% of the budget quota.
7. Regular maintenance and replacement of rechargeable batteries for memory chips: generally, the storage contents in some CMOS memory chips in the CNC system software of the machining center are maintained by the rechargeable battery power supply system when the power is turned off. Generally, lithium batteries or nickel cadmium batteries with rechargeable batteries are selected. When the working voltage of the rechargeable battery decreases to a certain value, the content will be lost. Therefore, the working voltage of the rechargeable battery should be maintained regularly. When the working voltage of the rechargeable battery drops to the specified value or there is an alarm of the working voltage of the rechargeable battery, replace the battery immediately. When changing the battery, it is generally carried out when the CNC system software is connected to the power supply, which is not easy to cause the loss of main stored parameters. Once the content is lost, you can type the main parameters again after replacing the rechargeable battery.

What is the composition of CNC machining center? It’s basically the above. Each part needs maintenance. Good maintenance will help prolong the service life of CNC machining center, save costs and help enterprises create more profits.
